Abstract: A long leg fixing device for a table that is erected using four long legs having a structure in which two of the long legs are linked by means of a crossbeam portion, and the two long legs are fitted to the table in such a way as to be capable of pivoting by means of a hinge, move together to open and close the legs, comprising: a base fixed to the table; a lever that swings around the arm pin inserted through the base; and an arm and a latch adapted to be interlocked with the swing of the lever; whereby said arm and said latch grip a seat portion mounted on a crossbeam portion. The device maintains the open-leg state by means of engagement with a component on the side surface of the linking crosspiece, and facilitates an operation to release a closed-leg state.

Abstract: The objective of the present invention is to provide a long leg fixing device which, while maintaining the conventional effect of suppressing unsteadiness when legs are open by supporting a bottom surface and a side surface of a linking crosspiece, maintains the open-leg state by means of engagement with a component on the side surface of the linking crosspiece, without relying on the elastic force of a spring, and at the same time facilitating an operation to release a closed-leg state, and a long leg fixing device 1 for a table 2 that is erected using four long legs having a structure in which two of the long legs 3 are linked by means of a crossbeam portion 4, and said two long legs 3 are fitted to the table 2 in such a way as to be capable of pivoting by means of a hinge 6, move together to open and close the legs, comprising: a base 12 fixed to the table 2; a lever 11 that swings around the arm pin 13 inserted through the base 12; and an arm 8 and a latch 9 adapted to be interlocked with the swing of the

Abstract: An object of the present invention is to provide a slant-adjusting unit which is convenient to adjust the slant of the flat plate supported by the legs and furniture having the unit. and a slant-adjusting unit 200, comprising a first spherical plate 210, second spherical plate 220 having an inner curved surface in facing relation to an outer curved surface of the first spherical plate 210, and a third spherical plate 230 having an outer curved surface in facing relation to an inner curved surface of the first spherical plate 210, and furniture 1, comprising a flat plate 100, the slant-adjusting unit 200 connected to any position of the flat plate 100, a column portion 300, and connected to the slant-adjusting unit 200, and the flat plate 100 integrated with the first spherical plate 210 to adjust the slant at will.
